테스트 할 SUP7이 없지만 SUP6 및 SUP32에서 작동합니다. SUP7이이 기능을 유지한다고 가정합니다.
JNPR M320 <-> SUP32 사이에서 테스트했으며 ' vlan mapping JNPR SUP32 '가 정상적으로 작동합니다.
QinQ가 필요하지 않습니다. QinQ 옵션의 기능은 상위 태그를 하나의 특정 태그에 추가하는 것입니다. 따라서 switchport vlan mapping 1042 dot1q-tunnel 42들어오는 [1042] 스택을 [42 1042] 스택에 매핑합니다. switchport vlan mapping 1042 42들어오는 dot1q Vlan [1042]를 dot1q Vlan [42]에 매핑 하는 것과 반대로 .
